By default, if you have an OS X device that’s connected to both Ethernet and Wi-Fi, it should prioritize the Ethernet connection over the Wi-Fi one. Sometimes it gets wonky though, in which case you’ll always be on Wi-Fi no matter what.
How do you fix such an issue? The steps are actually quite simple. First, launch System Preferences (using Spotlight is fastest ), then select Network:
At the bottom left of that window, look for the gear icon with the down arrow. Click on it to open the menu, then select Set Service Order:
Here you can drag-and-drop each item to change the priority order of your internet connections. Move Ethernet to the top to get the system to always use Ethernet over Wi-Fi when both are active. Wi-Fi will be a backup.
Click OK and then Apply and you’re done!
This is especially useful for when your Wi-Fi is unstable , but it’s also a good solution when your Wi-Fi is slow in general and there’s nothing you can do to improve the speed — when even this trick won’t work !
